To all whom it may] concern:

Be it known that I, WALTER F. NELsoN, a citizen of the United States of America,

lowing is a specification.

The object of this invention is to provide an improved construction for automobile tires in which the use of rubber or composition is omitted and a construction wholly provide an oil-tight casing adapted to contain yielding pressure devices and telesco 'ig and pivoted devices in an automobi e tire.

A further object of this invention is to My invention consists in the construction,

arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which' Figure 1 is aside elevation, partlyin section, of an improved wheel embodying my invention. Fig. 2 is an edge view, part1 in section, of the same wheel Fi 3 is 'a l ongitudinal section of a part of t e wheel, on an enlarged scale. Fig. 4' is a cross-section on the indicated line 4% of Fig. 1, onan enlarged scale. Fig. 5 is a cross-section on the indicated line 55. of Fig. 1, on an enlarged scale, and Fig. 6 is asection at right angles to Fig. 5 embodyingthe same elements. f

In the construction of the wheel as shown and the tire thereon the numeral 10 desig I prefer that the' ed outer end portions. A metal rim of circular form is made of counterpart annular members 12, 13 placed side by side and connected by screws 14 in staggered relations therein. End portions of the bolts 11 extend through the rim by means of apertures formed one-half in each member 12, 13 and are securedby nuts 15 on said bolts, which nuts are expanded against the inner surface of the rim.- The tire 16. primarily is formed-of a single piece of sheet metal and is generally of annular form and arcuate in cross-section on its tread or traction surface. The sides of the tire-are straight and 17, 18, which flanges are of -annular form and of materially less diameter than the tread or traction portion. The inturned flanges 17, 18 are of greater radius than' the rim and are arranged on either side thereof. Yokes 19 are screwed onthe threaded extremities of the bolts 11 and against the outer surfaces of the rim members 12, 13. The yokes 19 extend longitudinally of the rim and are formed with outstanding forks 20, 21 on their ends. Headed pins or studs 22, 23 are pivoted or hinged in and to the forks 20, 21 and extend in diverging planes from said fonks Yokes 24, identical in construction with the yokes 19, are fixed to and angularly of the inner face'of the arcuate portion of the tire 16 and headed sockets 25,

26 are hinged in theforks of said yokes 24 j and extend in diverging planes therefrom. The sockets 25, 26 receives pins 23, 22 respectively and the connection between said sock ets and pins'is telescopic and sliding. Expansive coil springs 27 are mounted on the sockets 25, 26 and pins 22, 23 and impine at opposite ends on the heads of said soiets and pins.

Itis the function of the springs 27 to yieldingly separate the arcuate portion of the tire 16 fromthe rim of the'wheel and provide a cushion between said tire and rim. The connection between the yokes '24.- and tire '16 is pivotal, thus permitting said yokes to turn into various angles relative to the cross-section of the tire in use. Counterpart casing rings 28, 29 are mounted within the inner surface of the tire. The casing rings 10 i are formed with integralinturned flanges and the flanges of said sockets contact loosely with thesurfaces of the flanges 33, 34 nearest to the rim of the tire. The sockets 37 are exteriorly threaded and nuts 38, fitted loosely to the bolts 11, are screwed on said sockets and bind the sockets rigidly to the flanges 33, 34. Sealing plates 39 are mounted between the flanges of the sockets 37 and the rim of the wheel and are formed with notches 40 in their ends partially embracing the spoke bolts 11. The sealing plates 39 are held normally-in sealing relations withthe flanges of the sockets 37 by screws 41 mounted loosely through the flanges 33, 34 and screwed into said plates. The flanged sockets 37, flanges 33,34, sealing plates 39, casing rings 28, 29 and flanges 30, 31, in conjunction with the inturned flanges 17, 18 of the tire 16, constitute and form an oil casing adapted to contain oil for lubrication of the springs, the sliding connections between thepins 22, 23 and sockets 25, 26, the pivotal connections between said pins and sockets and their yokes, the pivotal connections of the yokes 24, and the sliding connections between the sockets 37 and bolts 11. The sockets 37 and nuts 38 are so formed as to produce a cavity 42 around each bolt 11, which. cavity may contain suitable packing material, thus constimaaooa bolts 11?. Access is had to the interior of the tire by removing one or the other of the casing plates 28,29. Such removal is eflected by disconnecting the bolts 32, 41. and

30 and without removing the tire from the. rim or spokes.

pinging the same at their ends.

2. In a cushioned automobile wheel, the combination of a hub, spokes radiating therefrom and threaded on their extremities, a rim receiving end portions of said spokes, nuts on said spokes engaging the inner surface of said rim, yokes on end portions of the spokes and contacting with the periphery of the rim, ahollow metallic tire arranged concentric with the rim, yokes on the .inner surface of said tire, telescoping pins and sockets on said yokes, and expansive coil springs on said pins and sockets and impinging the same at their ends.
